“…They reported a mean intervention time of 108.5 min, which is in line with our mean intervention time of 107.8 min [18]. For elective standard percutaneous EVAR, a large meta-analysis reported mean intervention times to be approximately 108 min [19]. This underscores the notion that, though technically demanding, add-on sac and targeted rupture site embolization can be performed without significantly prolonging the intervention time, given the required level of expertise of the interventional radiologist.…”

Background Aneurysmal rupture in the aortoiliac segment is a severe, life-threatening condition. Nowadays, in addition to surgical treatment, the implantation of a covered stent graft constitutes a feasible, minimally invasive treatment option. A novel approach is the add-on of transarterial aneurysm sac embolization with N-butyl-cyanoacrylate (NBCA). Here, we report our experience of performing this add-on embolization procedure after endovascular aneurysm repair for complex ruptured aneurysms of the aortoiliac segment. Material and Methods We describe six patients (mean age of 75.2 years; all male) with ruptured aneurysms in the visceral aortic and aortoiliac segment in whom a high-volume transarterial aneurysm sac embolization was performed as an add-on therapy to the implantation of an aortic prosthesis. The aim of this add-on intervention was to achieve the definite embolization of the aneurysmal rupture site and to ensure the best possible aneurysmal sealing. We report the feasibility, technical success, and considerations of using NBCA as well as clinical and follow-up imaging results, given their availability. Results Technical success was achieved in all cases. Clinical success was achieved in four cases. No periprocedural complications or reinterventions were reported. The mean full procedure time was 107.8 min. The mean radiation dose was 12,966.1 cGy/cm2. A mean amount of 10.7 mL of NBCA mixed with lipiodol in a 1:3 to 1:5 ratio was used for all patients. Available follow-up imaging up to 36 months after the procedure showed no aneurysm progression or endoleaks. In two patients, the NBCA cast had almost fully dissolved over the course of follow-up. Conclusions Our study underscores the notion that aneurysm sac embolization using high volumes of NBCA with ethiodized oil as an embolic agent is a feasible and add-on treatment option for optimizing the exclusion of the aneurysm from patients with ruptured aneurysms in the aortoiliac segment.

Purpose: This single-center study aimed to assess patients who underwent intentional percutaneous endovascular aortic aneurysm repair (pEVAR) with Hybrid Technique combining a single Perclose (Abbott, Abbott Park, Illinois) Suture-Mediated Closure Device + single Angio-Seal VIP 8F (Terumo, Tokyo, Japan) and compare outcomes with the standard Dual Perclose technique. Materials and Methods: Consecutive elective pEVAR patients treated from November 2022 to November 2023, with healthy femoral accesses and introducer sheaths ≤20 French (F) outer diameter, were included. Coin-toss randomization determined whether a combination of single Perclose Device + single Angio-Seal VIP 8F (Hybrid Technique) or the standard double Perclose Devices (Dual Perclose) was used. In Hybrid Technique, a single Perclose device was positioned at 12 o’clock; a single Angio-Seal VIP 8F was placed after sheaths removal. Dual Perclose followed standard procedure. Primary endpoints included immediate hemostasis, sheath diameter differences, access conversion rate, technical success, and cost analysis. Results: The study involved 60 pEVAR patients (median age=78, interquartile range [IQR]=72–85 years) within the inclusion criteria. In 14 (24%) cases, only 1 femoral access was studied. There were 106 pEVAR accesses, with 58 (54.7%) in the Hybrid Technique group and 48 (45.3%) in the Dual Perclose group. Both groups exhibited homogeneity in pre-operative characteristics and sheath diameter (Hybrid Technique-16F vs Dual Perclose-18F; p=0.202). Immediate hemostasis was achieved in 100% of the Hybrid Technique group vs 87.5% for the Dual Perclose group (p=0.006). Surgical access conversion was unnecessary. Technical success was 100%, with all 6 femoral bleeding cases after Dual Perclose resolved endovascularly, using additional devices. Cost analysis showed a median cost of 330 euros (IQR=0) for the Hybrid Technique group vs 384 euros (IQR=360–456) for the Dual Perclose group (p<0.001). Thirty-day mortality was 3%, in 2 fragile patients, without access-related complications. Multivariate analysis identified Dual Perclose access (odds ratio [OR]=35.6; 95% confidence interval [CI]=18.3-36.8; p<0.001) and obesity (OR=19.7; 95% CI=1.4-23.9.5; p<0.001) as independent risk factors for immediate hemostasis failure. Median follow-up was 134 days (IQR=41–227), with 1 Hybrid Technique case (2%) successfully treated with thrombin injection for a small femoral pseudoaneurysm after 62 days. Conclusions: The elective Hybrid Technique with combination of single Perclose Device + single Angio-Seal VIP 8F during pEVAR in selected patients appears to be non-inferior to the standard Dual Perclose procedure. It demonstrates a positive trend in reducing immediate hemostasis failure and costs. Both procedures achieved technical success and avoiding surgical access conversions. Clinical Impact This study introduces a novel elective hybrid technique combining a single Perclose device with a single Angio-Seal VIP 8Fr for percutaneous endovascular abdominal aortic interventions. Results for hybrid technique showed 100% technical success and efficient immediate hemostasis, while costing less than standard dual Perclose procedure. Both procedures did not require surgical conversions. Despite being a single-center study, it demonstrates potential benefits of the intentional application of this hybrid technique towards minimally invasiveness. Obesity and dual Perclose technique were identified as independent risk factors for hemostasis failure, reaffirming the hybrid technique procedure’s efficacy as well as and non-inferiority to standard procedure.
